3 Claims. (01. 242-86) This invention relates to a fuel dispensing apparatus which is particularly adapted for servicing airplanes. More specifically, it relates to a fuel pumping and metering apparatus which utilizes a hose storing reel which is actuated by power in the hose retrieving direction.

It is an object of the invention to provide a dispensing mechanism wherein the fuel pumping motor is utilized to rewind the hose on the reel at the completion of dispensing.

It is a further object of the invention to provide a reel control mechanism whereby the reel is braked except when it is being actuated by the motor.

Still another object of the invention-is to provide motor control means which is automatically operated to thefofi position when the housing door is closed. 7 Yet another object of the invention is to provide a dispensing apparatus housing in which accessories, oils and other saleable commodities may be stored.

Still another object of the invention is to pr vide a power operated, foot controlled reel actuating mechanism.

These and other objects will become apparent from a study of this specification and the drawings which are attached hereto and made a part 3 hereof and in which:

Figure 1 is a front elevation of the dispensing apparatus with the parts mounted in their cooperative relationships.

Figure 2 is a side elevation v1ewed from the left of Figure 1.

Figure 3 is a side elevation viewed from the right of Figure 1.

Figure 4 is a side elevation of the switch operating mechanism with the switch in the off position. 7

Figure 5 is a view taken on the line 55 of Figure 1 showing the reel driving and control mechanism.

Figure- 6 is an exploded view of the treadle structure.

Referring now to Figures 1 to 3, the numeral I refers to a base which is preferably made up of angle irons 3 welded together and which supports angle irons 5 at the corners thereof. Central channel irons I are fixed to the base and support, with the elements 5, a top frame 9 made of angle irons.

Mounted on the base 1, adjacent and to the rightof the central channels (Figure l) is a base I I 'upon which is mounted a body I3 which houses the air separator, the usualscreens and a bypass valve. The screen which is not shown is disposed in a cavity which is closed by cap I 5 and the by-pass valve I8 is disposed in a cavity covered by cap II. A pump I9 is fixed on the body l3 and communicates with the screen chamber on the suction side and with the by-pass valve and air separator on the dischargeside.

This structure is .fully disclosed in the patent to Clement P. Griilith, Number 2,213,857, issued September 3, 1940.

A vent pipe2l leads from the gas outletof the separator through the rear wall 22 of the housing to an outlet fitting 23 which prevents the entrance of rain, etc., into the pipe.

Fixed to the rear side of body l-3 above the .pump is a motor supporting plate 25 which is braced at its upper end by a flat bar 21. The bar angle 5 on the right side and is bent at 29 and 3| .so that it will extend parallel with the plate 25. A motor 33 is fixed on the plate and is provided with a pulley 35 which is connected by belt 31 with pulley 39 on the pump IS.

A reel support is formed by members 4| and 43 which are mounted between the elements 5 on the left end of the frame (Figure l) and the central channels 1 respectively. Bearings 45 and 41 are mounted on the reel supports respectively and serve to support the journals on the reel 49. A rotary seal 5| is associated with bearing 45 so that liquid may pass from the stationarypipe 52 to the outlet hose connection 53 which is mounted to rotate with the reel and which receives the end coupling of hose 55. The other end of the hose is equipped with the usual valve controlled nozzle which is not shown. This hose is relatively long, that is, 50 or 100 feet or even longer. v

The flange 51 at the right end of the reel (Fig ure 1) is provided with an annular rim 59 of substantial depth. The inner surface of this rim is provided with a friction material 6| such as that used for automobile brakes. The material may be riveted to the rim in the manner usually followed in lining brakes.

As is clearly shown in Figures 2, 5 and 6, two brackets 63 are mounted on the rear angle 3 adjacent the rear channel I and to the left thereof (Figure 1). These brackets support the ends of shaft 64 which is fixed in the end of the long arm of an L-shaped lever 65.

Two aligned ears 66 are fixed on the end of the short arm of lever 65 and these ears are provided with aligned perforations 62 which are not tions 62 and the nut 13 and serves to support the" lever 63 for rotation. A jam nut may be provided to hold the shaft 31 in adjusted position.

The short end 14 of lever 63 is the portion which is engaged by the operator's foot when it is desired to rewind the reel.

The shaft 61 carries at its upper end a brake shoe 69. The shoe carries friction material ll which is adapted to be held in yieldable engagement with the exterior surface ofthe'rim 39 by means of a spring 13 which is anchored at one end to the lever 65 and at the other end to the member 43 disposed above the lever.

Intermediate the shaft 61 and bracket 33, a

pulley support 15 is fixed to the lever and ex-,

tends upwardly therefrom. This support carries a fixed spindle 16 which is directed toward the reel flange and which carries a pulley 11. Fixed to the pulley -is a friction wheel 13 which is adapted to engage the lined portion of the rim 53 to drive it. This wheel may have a friction material, such as leather, on its. exterior if desired.

The shaft 16 is so arranged that the friction wheel is not in engagement with the rim it when the lever 65 occupies its upper position under the action of spring 13.

A second pulley 3| is fixed to rotate with pulley 39 and is in the same plane as pulley 11 so that the latter may be driven from the former by means of a belt 33.

Two brackets 85 are mounted on the front angle 3 and a roll 31 is journalled in the brackets. The purpose ofthe roll is to prevent scumng of the hose as it is being retrieved by the power driven reel. The outlet pipe 83 from the separator is connected by pipe 3| with a water separator 93. The outletpipe 95 from this separator is connected to the inlet of a meter 31 by way of a combined check and relief valve 33. The meter isconnected by pipe IN to a sight glass I03 and the outlet of the glass is connected with the pipe 52 heretofore described.

The meter, water separator and sight glass may be of any desired form or construction.

A junction box IDS is provided for making the necessary electrical connections. A conduit I31 leads from this box to a switch I03 which is mounted at a convenient height upon a central frame member I.

An L-shaped switch operating rod 3 is connected at one end to a switch and rides in a guide 5 which is fixed to the front channel member I. The short end H1 or the rod is so positioned that the door H9 cannot be closed without contacting it when the switch is on. The switch is of the snap switch" type.

one on the left angle member 3 the other on the right angle member 5 (Figure 1). The

Operation The operator in servicing a plane will unlatch the left-hand door H8 and swing it open. This gives him access to the.switch rod 1 which he pulls to actuate the switch I09 which, in turn,

, energizes the motor 33. He will also move the outer treadle lever 63 into the. extended position. Since the nozzle valve is closed, the fuel will be by-passed from the pressure side of the pump back to the suction side through the by-pass valve. a

The operator may then remove the nozzle from peg I35 and draw the hose off the reel to the plane 'whichis to be serviced. This'action is resisted frictionally by the brake '33 which Another conduit 13! leads to a switch I23 and a lamp socket I33 which is controlled by the switch. Anelectric lamp I21 furnishes the light for the cabinet interior.

Pairs of small angles I23 and I3! are-fixed to the central channel members l1. and the corrides on the rim 5! of reel flange' 51 under the action of spring 13. The resistance is sufiicient toprevent spinning of the reel after the pull has been relaxed but not great enough to require extraordinary exertion on the part of the operator.

When the nozzle tip is inserted in the fuel tank, and the nozzle trigger is pressed to open the nozzle valve, fuel will be drawn by the pump from the storage tank and since the by-pass valve will close, liquid will be delivered to the air separator in 13, the water separator 53, the valve 38, meter 31, sight glassl03, pipe 53 into the reel, through connection 53 to hose i5 and thence to the nozzle where it is discharged. I

When the required amount of fuel has been dispensed as shown by the register on the meter, the nozzle valve will be closed andthe operator will return to the apparatus carrying the nozzle.

He will then depress the treadle lever -43 with his foot. This releases the brake 59 from the rim 53 and at the same time causes the friction wheel 19 to engage the lining 6| on the insideof the rim. The rotation of motor 33 will accordingly be transmitted through pulley 33, belt 31, pulleys 33 and 3|, belt 33, pulley 11 and friction wheel i3 to the reel.

The speed at which the hose is retrieved may be varied .by varying the pressure upon the treadle. The hose may be held up from the roll 31 and guided onto the reel by the operator or it may be permitted to feed itself onto the reel. In the latter case, the roll 31 prevents the angle 3 from scumng the hose. V

when the hose is substantially all rewound the operator will place the nozzle on the peg I35. Another application of pressure on the treadle will then take up the slack hose and upon release of the treadle, the brake]! will again become effective to hold the reel against unwinding; The switch rod 1 may then be pushed in to stop the motor."

The outer treadle lever 33 will then be pivoted to a position substantially parallel with and.1nside of the door so that the door maybe closed and latched. If the switch has not been opened,

the door will not close completely so that the operator will be wamedoi the condition and can actuate the switch to the ofl" position.

The right-hand door gives access to the' limited to the specific embodiment disclosed herein primarily for purposes of illustration; but instead, they desire protection falling fairly within the scope of the appended claims.

What we claim to be new and desire to protect by Letters Patent of the United States is:
